void XMLElement::addChildtoVec ( XMLElement * children )

Add an element to children vector. This function push_back the element to the children vector

Parameters

children is a child element to add

Definition at line 475 of file XMLElement.cpp.

void XMLElement::getAttribute ( string strLine )

This function is to get attributes in a strLine by searching for an equal sign in each line. If an equal sign is found, take elements on the left as the key and elements on the right which is between the double quot as value. Then store it into a vector of an attribute.

Parameters

strLine

Returns

Definition at line 335 of file XMLElement.cpp.

int XMLElement::GetLineNumber ( ) const

Get a line number from each line of the XML File.

Definition at line 467 of file XMLElement.cpp.

string XMLElement::getStrContent ( ) const

Get a string content.

Definition at line 471 of file XMLElement.cpp.

string XMLElement::getStrElement ( )

Get a string element.

Definition at line 44 of file XMLElement.cpp.

vector< Attributes * > XMLElement::getVecAttribute ( )

Get the vector of attributes.

Definition at line 487 of file XMLElement.cpp.

vector< XMLElement * > XMLElement::getVecChildren ( ) const

Get the vector of children.

Definition at line 491 of file XMLElement.cpp.

ParserState XMLElement::GetXMLData	(	int	nLineNo,
		string	strLine,
		string &	strElementName,
		string &	strContent,
		int	nStartPos,
		int	nEndPos,
		ParserState	currentState
	)

This function parses a line read from the XML file and returns the appropriate data for that line. N.B. Assumptions: (1) The XML file being processed must be well-formed. (2) There is at most one complete element per line. (3) All element opening tags start on new lines. (4) The element closing tag, if present, is the last thing on a line. (5) If there is no element closing tag on the same line as an element opening tag, there is no content on that line. (6) Attributes and their values are ignored.

Parameters

strLine	line read from XML file
strElementName	name of element found
strContent	content of an element
nStartPos	position at which to start search
nEndPos	position at which search ended
currentState	state of parser on entry into this function

Returns: state of parser on exit from this function

Definition at line 144 of file XMLElement.cpp.

int XMLElement::ReadFiles ( string strFileName )

This function reads the file passed to it as a parameter.

Parameters

strFileName name of file to read

Returns: status flag, EXIT_SUCCESS = good

Definition at line 98 of file XMLElement.cpp.

string XMLElement::reverseString ( string str )

ReverseString function is to reverse string elements and this is used for reversing strContent after backwardly stored This code was token from the cplusplus web-site http://www.cplusplus.com/forum/beginner/68197/

Parameters

str	is an argument of the string content that has stored backwardly

Definition at line 399 of file XMLElement.cpp.

void XMLElement::SetStrContent ( string strContent )

Set the string content

Parameters

strContent is the content to set, read from the XML file

Definition at line 479 of file XMLElement.cpp.

void XMLElement::SetVecChildren ( vector< XMLElement * > vecChildren )

Set the vector of Children

Parameters

vecChildren

Definition at line 483 of file XMLElement.cpp.

void XMLElement::ShowAttributes ( vector< Attributes * > vecAttr )

This function takes the vector Attribute and print out all the attributes that been stored

Parameters

vecAttr is the attribute vector

Definition at line 450 of file XMLElement.cpp.

void XMLElement::ShowXMLTree	(	XMLElement *	elem,
		int	treeLevel
	)

In this function, I have used Prof. Jesse Heines's code and modified couple things to make this function works the way it should be.

This function prints the XML tree as required by Assignment No. 4. It is called recursively when a child Element itself has children.

Parameters

elem	the current Element to process
treeLevel	the indentation level

Definition at line 416 of file XMLElement.cpp.

string XMLElement::trim ( string & str )
